TONY JONES, PRESENTER: Farmers are urging the Prime Minister not to sign up to any free trade agreement with Japan unless there's a better deal for beef and dairy producers.With the Prime Minister heading to Tokyo at the weekend, there's growing concern that agriculture may be the loser.But the Trade Minister's told the ABC there'll be no handshake until Japan gives more ground.Eliza Borrello reports.ELIZA BORRELLO, REPORTER: The Japanese have a taste for high end Australian cheese and Adam Jenkins wants them to eat more of it.The Prime Minister's off to Tokyo on Saturday and the Victorian dairy farmer wants him to be driving a hard bargain.ADAM JENKINS, FARMER: I would be making sure that everything he possibly can that he can do to get as much market access for us as possible. Otherwise, it's not worth it.ELIZA BORRELLO: The deal would be a big win for Tony Abbott, but farmers don't want it signed unless beef and dairy tariffs are slashed.ADAM JENKINS: I'd be very disappointed at our government for agriculture to be signing something that doesn't deliver something significant back to agriculture and I think they need to be really working really hard and mindful of that.ELIZA BORRELLO: In some cases, the tariffs are in excess of 35 per cent. The Trade Minister's confident a deal is close, but is adamant it won't be signed unless the barriers come down.ANDREW ROBB, TRADE MINISTER: They're our biggest market for both beef and dairy. There's a lot more we could do there. We're very good at those - production of those products, we're very competitive on a world basis and they are fundamental to any agreement.ELIZA BORRELLO: The ABC's been told the Japanese and Australian negotiating teams are still miles apart when it comes to beef and dairy tariffs. One industry player says Japan's a notorious minute-to-midnight negotiator and doesn't want the Prime Minister backing down for the sake of going home with a deal.DAN TEHAN, LIBERAL BACKBENCHER: If we are to have a proper free trade agreement, the Japanese need to understand that in the area of agriculture, that needs to be included and we need to see serious reductions in that space as well.ELIZA BORRELLO: While the Government's trying to boost access to the Japanese market, entry to another's been cut off. Russia's banned Australian beef imports, blaming a growth hormone. Barnaby Joyce says it's a baseless excuse.BARNABY JOYCE, AGRICULTURE MINISTER: I think it's to do with other political circumstances that are currently about and obviously the issue in the Crimea would have something to do with it.ELIZA BORRELLO: He wants the ban lifted, but says he's focused on developing other markets.Eliza Borrello, Lateline.
